CAP FOR BOTTLES,

To all whom it may concern:

Be it known that I, CHARLES FRANCIS JENKINS, citizen of the UnitedStates, residing at Washington, in the District of Columbia, haveinvented certain new and useful Improvpmentsin Caps for Bottles,

of which the following is a specification,

able.

In the accompanyin drawin s Figure 1 is a side elevation of acylindrical bottle with the novel cap in place thereon. Fig.

2 is a vertical diametricalsectionof the cap. Fig. 3 shows in sideelevation a portion of a slightly modified cap.

In these figures, 'A' represents a paper bottle of any approvedconstruction, and B a cap for closing the mouth of the same. This capconsists of a disk preferably of paper primarily circular in generaloutline, but with preferably four projections C at quadrantal points.Each disk has its marginal portion drawn by dies in such manner as toconvert the disk into a cup having a plane central body from which risesan integral annular flange which is, bent back upon itself and extendspreferably below the plane of the body portion. The form is such that inpressing the cap upon the bottle the upper margin of the latter entersand fits snugly between the rising portion B of the flange and thedescending portion B while its upper edge is covered by the curvedportion B which integrally connects the portions B, B All three portionsaid in securing non-leaking closure, and all three strongly resist anyforce tending to distort the upper part of the bottle, either bybattering it or springing itinwardly or outwardly from circular formQ Ata short distance within the outer limit of each projection the disk iscut to form atab'D, and preferably a small segment at the free end ofeach tab is removed to facili- Specification of Letters Patent DISTRICTOF COLUMBIA, ASSIGNOR, BY PACKAGE CORPORATION OF AMERICA,

ward, when they form a convenient means for liftin or pulling the capfrom the bottle. Pre erably they extend very nearly to the portionB ofthe c'ap so that the cap is not readily. torn by bending them upward andthen pulling them with all necessary force. By forming the cap with thepro. jections, the tabs may be made long without unduly enlarging thedisk, and at the same time the lower free marginal portion of the capmay be left unbroken, to act like a hoop about the upper part of thebottle. shows tabs D out free at their upper instead of their lowerends, so that they need not be materially bent before using them fordrawing the cover upward.

What I claim is:

-1. A bottle cap provided at its margin with parallel flanges adapted tofit, respectively, the interior and exterior surfaces of an open bottle,the outer flange being provided with integral tabs above the lowermargin'of the flange by which the cap may be drawn from the bottle.

2. A bottle cap provided with a dependent marginal flange out throughabove its free margin to form integral tabs free at their upper ends.

3. A bottle cap provided with a dependent marginal flange cut throughupon opposite sides above its free margln to form integral tabs abovethe bottle-encircling band formed by the uncut .free marginal portion ofthe flange. A I

4. A one-piece bottle cap having its marginal portion bent from theplane of the body of the cap, to form a cylindrical flange and againdoubled back to form a second like flange concentric with the first andat a distance therefrom substantially equal to the thickness of the wallof a bottle upon which it is to be placed, said second flange being cutthrough above its free margin to form tabs shorter than the openings inwhich they normally lie.

In testimony whereof I affix in presence of two witnesses.

CHARLES FRANCIS JENKINS.
